UL 2010原文

5.2 Electrical properties

5.2.2 Dielectric strength for all finished types

The individual insulated conductors of finished flexible cords and cables shall be capable of withstanding

for 1 min, without breakdown, the application of an alternating (rms) voltage as indicated in Table 46

between each insulated conductor and between the insulated conductors and any other conductive

components and ground, on a specimen at least 15 m (50 ft) in length. All ²W² Type cords shall be

conditioned in water for a period of at least 6 h prior to testing. All indoor cords shall be conditioned in air

at room temperature for a period of at least 6 h prior to testing.

For all ²W² Type cords, the dielectric strength test shall be performed in accordance with the test,

Dielectric Voltage-Withstand Method 1, in CAN/CSA-C22.2 No. 2556, UL 2556, or NMX-J-293-ANCE.

For all indoor type cords, the dielectric strength test shall be performed in accordance with the test,

Dielectric Voltage-Withstand Method 1, in CAN/CSA-C22.2 No. 2556, UL 2556, or NMX-J-293-ANCE

except without immersion in water.（不需要浸水）

各位大蝦，UL62 室內(nèi)電線耐壓試驗是不是不需要浸水？

except without immersion in water.（不需要浸水）

這句話怎麼理解呢？------------除了不需要浸水的外（就是指有屏蔽的吧？），其他的都參考Dielectric Voltage-Withstand Method 1, in CAN/CSA-C22.2 No. 2556, UL 2556, or NMX-J-293-ANCE

純蒙的。。。。。

單芯無屏蔽就需要     其他不需要
